Based on a ‘zeilersforum’ topic I found this question discussed: “Blue Smart IP22 charger trips automatic fuse” in this community.
Summary: a IP22 12/30 will trip a 6A and 10A fuse and not a 16A. So, you may need an inrush limiter as proposed by Victron.
In the same discussion Victron added that this phenomina has been discussed while preparing the IP65 design.
Old harbours may be fused at 6A or 10A rather than 16A. The shore fuse may not be accessable after it trips (a reset will do, if accessable).
1:-is the IP65 12/25A model year 2021 adapted in a way to limit the inrush current to 5A or such that a 6A fuse will not trip?
2:-to which save fuse size have the IP65 improvements result in: are 6A and 10A tested?
3:-if not, is Victron willing to test this (or these) charger(s) in order to document needed fuse level and inrush limiter recommendation?
4:-is there a Victron approved hardware interface or schematic with component list available for save use at 6A fuses (a 5A inrush limiter)?
5:-neither manuals are prescribing an “aansluitwaarde” (current supply level) and do not warn for low level harbour fuses. The charger will only take 1.5A average so this inrush is very unexpected. Will you update the manual or supply an addendum on the product tab of the website?
We have a seagoing trailer sailer located in the Netherlands and are planning sailing from remote locations next year, where neither 16A nor 24/7 harbour master may be obvious. The IP65 12/25 is the main charging source for the lfp battery.
Please add the question numbers as a reference to your answers. Thank you.
